Calibration of a Calorimeter for Thermal Resistance Measurements of Advanced Insulation Panels. Reprinted from HVAC and R Research, Vol 6, No. 3

摘要

Insulation technologies are being developed to reduce the energy consumption associated with refrigerators, freezers, and the transport of refrigerated products. Among the insulation concepts being explored are powder. foam, glass-fiber-filled evacuated panels, and low-conductivity gas-filled panels. These advanced insulation panels offer the potential for significant reductions in energy consumption and greater flexibility in product design. Unfortunately. the equipment used to determine the thermal resistance oftraditional building insulation materials is not well suitedfor measuring the thermal resistance ofadvanced insulation panels. This paper describes a calorimetric apparatus to measure the thermal resistance ofadvanced insulation materials. It presents the procedures used to determine the thermal resistance of advanced insulation panels. and compares the calorimetric results to measurements from the guarded hot plate for extruded polystyrene specimens. The measurements agree to within 3 percent. over a mean temperature range of280 to 295 K.
